Concept Search - What can I type?

For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.

Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

Abstract

A control process in a diskette adapter detects and reports hardware failures when the adapter is not in use. When the adapter has no work requests active or pending, a 5-minute timer is started. To assure the device will not be needed immediately, the timer permits human intervention. If a new work request is received, the timer is disabled. Should the timer expire, the background diagnostic function is enabled. (Image Omitted) The diagnostics are divided into small, independently-executable packages with checks for work between packages to minimize user wait time. Reliability of the I/O device is improved such that the device can continuously detect and report hardware failures without system intervention. At the completion of a command, the adapter checks for any active or pending tasks.

Background Diagnostics in a Diskette Machine

A control process in a diskette adapter detects and reports hardware failures
when the adapter is not in use. When the adapter has no work requests active or
pending, a 5-minute timer is started. To assure the device will not be needed
immediately, the timer permits human intervention. If a new work request is
received, the timer is disabled. Should the timer expire, the background
diagnostic function is enabled.

(Image Omitted)

The diagnostics are divided into small, independently-executable packages with
checks for work between packages to minimize user wait time. Reliability of the
I/O device is improved such that the device can continuously detect and report
hardware failures without system intervention. At the completion of a command,
the adapter checks for any active or pending tasks. If there are no active tasks, a
value of 5 minutes is loaded into a timer. The positive timer value indicates to a
timer routine to begin a countdown of the 5 minute timer. The timer routine
executes every 1.0 millisecond and is driven by an interrupt. The interrupt is
generated by a hardware timer. If at any time a command interrupt is received, a
value of zero is loaded into the timer and a diagnostic flag is reset. This indicates
to the timer routine to stop the countdown. If an asynchronous response should
be required (such as an address switch change), the timer continues to count
down but the diagnostic calling routine will not be invoked until the response is
sent. If the timer expires, the diagnostic flag is set indicating that the background
diagnostics are allowed to run. A monitoring routine recognizes the background
diagnostic flag and gives control to a background diagnostic calling routine. The
background diagnostic calling routine separately calls one of the ten diagnostic
routines. The diagnostic routine invoked by the calling routine tests a given
portion of the hardware and indicates to the background diagnostic calling routine
successful or unsuccessful completion. If everything is normal, the background
diagnostic calling routine returns control to the monitoring routine. The monitoring
routine then determines if background diagnostics are disabled by an incoming
command or suspended by a pending asynchronous response. If not disabled or
suspended, the background diagnostic calling routine receives control again, a...
